Changing Speakers help @#$%^!

Hello again,
 
   Do any of you have a link that shows the steps to change the front and rear speakers on a 99 accord?
 
I'm installing new speakers and I believe you need adapters.... Also it would be nice to know how to remove them!!
 
Second, I just got a sub box and amp....I have a stock cd player....Is there anyway of hooking this or do I have to go aftermarket for the radio as well.
 
PLEASE HELP!!

have you checked in the DIY section?

I dont knnow about the speakers,  Have not done them yet. 
 
But about the amp, you can replace the stock head but you will regreat it.  Especially if you have CC.  Im getting a rockford fosgate 3sixty.  Its a preamp processor that lets you run amps and such off a OEM head, plus it has a more advanced EQ.  Lots of little trick things too like Bluetooth connectivity to a plam pilot.
 
Here is the link

for the front and rear component speakers, its a direct plug and play, you shouldnt need an adapter? for the rear, i believe you can access them for the trunk, unscrew, then screw in the new ones, for the door ones, you need to take off the panels, unscrew, and then screw in the new ones, if i'm wrong, correct me, cuz this is what i did for my camry, dont know about adapters or anything..
 
and as far as the headunit goes, the stock one won't cut it, getting a new one, will have more power and more features
